Background technology
Life with produce in the organic solvent highly volatile of extensive use become gas, so have another name called volatile organic matter (Volatile Organic Compounds, VOCs), and the VOCs of majority has certain toxicity to human body, must handle; Wherein, The incineration method is a kind of of VOCs exhaust-gas treatment mode; VOCs clearance under proper condition can reach more than 99%, and the product after the burning is generally water, carbon dioxide, nitrogen oxide, oxysulfide etc., so be a kind of method that can effectively handle VOCs contained in the waste gas; Yet; Generally can with rotary-type inspissator (Rotor type rotary concentrator), revolving ring type inspissator (Carousel type rotary concentrator) or fluidized bed inspissator (Fluidizedbed concentrator) or fixed-bed type inspissator VOCs waste gas be concentrated earlier; Send into the incinerator purified treatment to the VOCs waste gas that concentrates again; Adsorb-concentrate desorption-three continuous programs such as incineration and utilize; Make VOCs be cracked into harmless water and carbon dioxide, and utilize inspissator to promote the incineration usefulness of incinerator.
(1 to 10RPH because of the drive of reductor (Ceared motor) is rotated for runner (or change) formula inspissator; Major part is 2 to 6RPH), runner (or change) formula inspissator is positioned at the adsorbent of adsorption zone, is the absorption program of carrying out the phase I, and VOCs waste gas is adsorbed at normal temperatures, and purified gas directly is disposed to atmosphere; And along with the rotation of runner (or change) formula inspissator; When the adsorbent behind the absorption VOCs waste gas goes to the desorption district; Promptly get into the desorption program of second stage; The hot-air that this desorption program is required is by (about 160 to 300 ℃ of the preheated air of cooling zone outlet and the hot-airs after the incinerator heat exchange of rear end; Major part is 180 to 220 ℃) provide; The mat hot-air concentrates desorption from the adsorbent that gets into the desorption district with organic matter and comes out; The pollutant levels of effluenting this moment are approximately about 5 to 20 times of the waste gas that becomes a mandarin, and the organic matter that desorption comes out then can carry out high temperature (more than 600 ℃ at the incinerator of phase III; If catalyst direct combustion stove then is 200 to 450 ℃) incinerate, so can reduce follow-up exhaust-gas treatment unit size, and save and just establish expense and running expense.
Yet; As shown in Figure 1; Existing volatide organic waste gas treating system, it handles the process of volatile organic waste gas, is the adsorption zone 31 that the rotary-type inspissator 30 of flowing through pumped volatile organic waste gas by mat one first blower fan 11; It is adsorbed to cause organic substance in the volatile organic waste gas to be positioned at the adsorbent of adsorption zone 31, and the Purge gas after the adsorption treatment is then through these first blower fan, 11 dischargings; After this; When the adsorbent of adsorb volatile organic exhaust gas goes to desorption district 32; Then will through the desorption air-flow of one second heat exchanger 20b heating by one second blower fan 12 pump through, be adsorbed agent adsorbed organic matter matter because of receiving thermal desorption in concentrated air-flow, this concentrated air-flow is led to one first heat exchanger 20a preheating again; Direct-fired incinerator 40 burnings are cleaned into water and carbon dioxide is main material and import; Purifying gas flow after the burning is undertaken by this first heat exchanger 20a and this second heat exchanger 20b after the recuperation of heat, externally discharging, or even undertaken just discharging after the recuperation of heat by one the 3rd heat exchanger 20c again; Wherein, the combination of this direct-fired incinerator 40 and the first heat exchanger 20a can be described as recovery formula direct combustion incinerator (RecuperativeThermal OxidiZer).
Moreover; Existing volatide organic waste gas treating system; Usually can adopt shell-and-tube gas as shown in Figure 2 to gas-heat exchanger; Be 21 two ends to be restrained in air guide be welded on two location- plate 22a, 22b; And two location- plate 22a, 22b are fixed on a shell body 23 inner stage casings, cause this shell body 23 by the district at a distance from the heat-exchanging chamber 232 in the first gas inlet plenum 231 of leading portion, stage casing and the first gas discharge chamber 233 of back segment, make this shell body 23 be formed with first gas inlet 234 again at the shell wall of the first gas inlet plenum 231; This shell body 23 is formed with second gas inlet 235 and second gas outlet 236 at the shell wall of heat-exchanging chamber 232, and this shell body 23 is formed with first gas outlet 237 at the shell wall of the first gas discharge chamber 233.So first gas flow gets into the first gas inlet plenum 231 by first gas inlet 234, the air guide tube bank 21 of process heat-exchanging chamber 232 is managed interior and is flow to the first gas discharge chamber 233 then, is derived by first gas outlet 237 again; Second gas flow then gets into heat-exchanging chamber 232 by second gas inlet 234, and outside the pipe of air guide tube bank 21, flows, and to let first gas and second gas carry out heat exchange at this, is derived by second gas outlet 236 again.
Yet, because existing shell-and-tube gas to gas-heat exchanger, adopts the horizontal welded-fixed monolithic design that air-flow once flows in the air guide tube bank 21 usually; So, because of the air-flows in its air guide tube bank 21 of flowing through only once flow, cause the time that is used to carry out heat exchange shorter, also be that the heat exchanger effectiveness that reached is relatively poor; And horizontal welded-fixed design kenel then causes cleaning in the future comparatively difficult, and can influence air-tightness because of thermal strain causes malformation, and further influences efficient; Again; When a heat-exchange system (such as aforesaid volatide organic waste gas treating system) must be used several heat exchangers simultaneously; Existing shell-and-tube gas to gas-heat exchanger then because of the design kenel of monomer whose; And setting is drawn and is established relative air guide pipeline individually, is difficult to then integrate and take up room.
